Suspend to RAM =3D=3D STR =3D=3D suspend =3D=3D sleep
Suspend to disk =3D=3D hibernate

Both are available in Linux. It all depends on whether you use APM=20
(suspend, hibernate) or ACPI. The difference between them is that with=20
APM the BIOS cares for most parts of the power savings while with ACPI=20
the operating system has to do the work.

=2D-=20
There is still the danger of EU software patents!
